无法在新计算机上迁移旧项目

Question

当我尝试在新计算机上迁移旧项目时出现错误。在旧计算机上，数据库运行良好。数据库的内容并不重要，这就是为什么我没有将旧数据库作为 .bak 文件带到新计算机上的原因。这是一个学校项目。

我的工作地点：

对比 2015。

ASP.NET核心

"Microsoft.NETCore.App": {
  "version": "1.0.1",
  "type": "platform"
},

"frameworks": {
"netcoreapp1.0": {
  "imports": [
    "dotnet5.6",
    "portable-net45+win8"
  ]
}
  },

这是来自 VS PackedManager 的错误代码：

我在网上搜索了解决方案，但没有找到任何我认为可以使用的解决方案。我正在使用 SSMS 2016 最新版本来处理数据库。

很高兴知道我目前在同一台计算机上使用虚拟机在学校工作。我正在使用 VMWare，并且在虚拟机的 WAC 服务器上安装了 SQL Server Express 2012。我不知道这是否对我当前的问题有任何影响，但我认为你知道的越多，你能提供的帮助就越大。当我处理这个问题时，虚拟机不是运行。

告诉我你是否还有其他任何想要查看我的代码的地方。

问题终于解决了。我完全重置了 windows 10。并安装了 VS 2017。然后一切正常。我还做了一个新的测试项目并尝试迁移它。但同样的问题不断出现。所以我认为它必须是某个地方的一些损坏的文件。但正如所提到的，现在一切正常。感谢所有的建议。
